Harrison Beck and Uncle Nat climb aboard the night train to Narvik, travelling to the Arctic Circle to see the northern lights for Christmas.

Journeying into the never ending night of the arctic winter, our railway detectives must outsmart an assassin in their most chilling adventure yet, in which nothing is as it seems.
